Kohei Nakajo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Data recording device, data recording method, data editing device, and data editing method
    Patent number: 7421189
    Abstract: An original coded stream reproduced from a magnetic tape is decoded by an MPEG decoder, and original video data of a base band is thus generated. A switching circuit generates edited video data by switching the original video data and supplied insertion video data on the base band level at IN-point and OUT-point. The MPEG encoder generates an edited coded stream by coding the edited video data supplied from the switching circuit. A system controller controls a recording circuit to record a picture changed by editing processing, from among the edited coded stream, onto the magnetic tape.

  • Data recording device, data recording method, data editing device, and data editing method
    Publication number: 20040264923
    Abstract: An original coded stream reproduced from a magnetic tape 1 is decoded by an MPEG decoder 29, and original video data of a base band is thus generated. A switching circuit 15 generates edited video data by switching the original video data and supplied insertion video data on the base band level at IN-point and OUT-point. The MPEG encoder 19 generates an edited coded stream by coding the edited video data supplied from the switching circuit 15. A system controller 13 controls a recording circuit 23 to record only a picture changed by editing processing, from among the edited coded stream, onto the magnetic tape.
